AbstractField studies of the benthic macroalgae of fifteen selected Chesapeake Bay oyster communities were conducted over a period of a year (March 1977 to February 1978). Algal distribu tion and seasonal occurrence were studied in relation to changes in the physical environment. Salinity, temperature, and light availability were important factors in the spatial and temporal distributions of algae in these subtidal habitats.Seventeen species of Chlorophyta, Phaeophyta, and Rhodophyta were recorded from the fifteen study sites distributed over 130 kilometers within the Maryland portion of Chesapeake Bay. Species of Chlorophyta were associated with oyster communities throughout the year of study with maximum numbers of species and maximum biomass occurring in spring. Only once was a member of the Phaeophyta encountered; a single filamentous species, Ectocarpus, was collected during winter. Species of Rhodophyta were present throughout the year at the study sites.Most of the algae collected reproduced asexually by spores and/or vegetative fragments. Sexual reproduction occurred in some of the red algal species. The presence of tetrasporic and cystocarpic plants of Dasya baillouviana and Polysiphonia harveyi var. olneyi may indicate that the usual triphasic Florideophycean life history occurs in this estuary.

Abstract The light-harvesting phycobilisome complex is an important component of photosynthesis in cyanobacteria and red algae. Phycobilisomes are composed of phycobiliproteins, including the blue phycobiliprotein phycocyanin, that are considered high-value products with applications in several industries. Remarkably, several cyanobacteria and red algal species retain the capacity to harvest light and photosynthesise under highly selective environments such as hot springs, and flourish in extremes of pH and elevated temperatures. These thermophilic organisms produce thermostable phycobiliproteins, which have superior qualities much needed for wider adoption of these natural pigment–proteins in the food, textile, and other industries. Here we review the available literature on the thermostability of phycobilisome components from thermophilic species and discuss how a better appreciation of phycobiliproteins from extreme environments will benefit our fundamental understanding of photosynthetic adaptation and could provide a sustainable resource for several industrial processes.

A New Species

Using mitochondrial COI-5P and plastid rbcL genetic markers, the red algal species historically known in southern New England, USA, as Champia parvula is found to be genetically distinct from the species to which it has historically been aligned. This necessitates the description of a new species, C. farlowii, for plants from Rhode Island, Massachusetts, Connecticut and New York, USA. The new species is morphologically compared with true European C. parvula and congeners, especially those with similar features previously aligned under the same species name. Champia farlowii is a morphologically cryptic species, the sixth in the expanding C. parvula complex, with overlapping characteristic measurements despite differences at the range extremes, when compared to C. parvula.

Morphological Differences

Based upon COI-5P, LSU rDNA and rbcL sequence data, as well as its morphological characteristics, a new red algal species, Eucheumatopsis sanibelensis E.S.Peterson, C.W.Schneider et G.W.Saunders sp. nov., was discovered on the Gulf coast of Florida, USA and shown to be distinct from the generitype E. isiformis with a type locality in the eastern Caribbean Sea. The new more attenuate taxon from Sanibel Island represents only the second species in this newly described genus, a genus recently segregated from Eucheuma based upon significant molecular and morphological differences. The two species have overlapping geographic distributions in the eastern Gulf of Mexico, but thus far E. sanibelensis is only known from a single location.

Length Frequency Data

Variation in the abundance of Barleeia unifasciata is compared in several red algal species between June 1978 and June 1980 at Cooskeen Cove, Bantry Bay, Ireland. Population abundance in all algae varied seasonally, exhibiting a cycle of late-summer to autumn maxima, with winter to early summer minima. Greatest abundance was recorded in those algae which formed compact turf-like growths suitable for the entrapment of diatoms and detrital material and provided greatest shelter from wave-crash. Length frequency data showed the main recruitment period to be late June-October with a peak in August with juveniles present in all months of the year. Maximum life span was shown to be 2 years or more with only 15 % of the population surviving into the second year. Sexual development and reproductive cycle was determined for 0 + and 1 + animals. Mature males produced sperm continuously throughout the year. Not all 0 + females spawned in their first year. Summer spawning 0 + females exhibited reduced sexual activity in October and spawned again in the following summer. Some 1 + females spawned in winter and spring. Delayed sexual development in some individuals of both sexes was related to late hatching.

First Time

A red algal species,Polyneura bonnemaisonii(Delesseriaceae, Rhodophyta), is described for the first time in the Atlantic Ocean of Morocco. This is also the first reference of the occurrence of this species in Africa. This species was collected in the lower intertidal to subtidal zones, from Hyayda (north-west of Morocco). The Moroccan specimen is studied in detail and compared with other closely related species. Habitat, geographic distribution, description and illustration of the macroscopic and microscopic characters are presented and discussed in this work.
